What were the baseline numbers? Dyno numbers taken after you do stuff don't mean much unless you have something to compare them too. In this case, stock numbers should be about 130 -135 whp for a 2.0, maybe 140 with just an SRI and pod filter.....so near $2k in bolt-ons for less than 10 hp. Axle back, a decent intake and a good tune will put you closer to 170 whp....outside of that there isn't much you can do with this motor that has any real significant effect, and changing the exhaust pipe diameter by swapping the resonator and/or mid pipe can actually cost you some power. Lots of discussion on this stuff if you read through this section of the forum.....
 
The throttle body upgraded is one of the best bang for you buck upgrades you can do to these cars, improves throttle response a lot. I also have the best intake available for these cars currently.
The best bang for the buck is a proper tune.....bar none. A good tune will include real throttle pedal remapping and greatly improves response....
I don't see how that intake is superior to any other. More expensive ≠ better....Its just a fancy SRI with a pod filter and an air box.....There is no way that the claim of a 71% flow increase is valid. Peak attainable flow and actual engine demand are two very different things. The engine can only draw in as much air as is dictated by cylinder volume, you can't increase air flow 71% just by using a different air filter. In fact, increasing the intake flow by 71% would require a complete ECU remap for the engine to run....The OEM intake is already quite efficient by design, and flows just as well as any aftermarket part. I hardly think that the $345 intake linked to above provides any additional airflow beyond what any other decent tube and pod SRI can provide.
